There are two primary operational differences between these types of installations that affect multilateral procedures; for subsea installations these differences are the presence of heave and a riser...

...Detailed Design Review The novel metal-to-metal sealing and anchoring system was designed to set and seal inside the operator's 10.125-in., 81-lb/ft casing and to hang 7.75-in., 46.1-lb/ft liner. The basis of design was the service provider's ISO 14310/API 11D1 V1-Type qualified hanger...

... application. In addition, it is unable to determine the actual vibration amplitude of BHA (Chen 2007 ). Abstract Operators of Gulf of Mexico (GOM) wells frequently reported overtorque issue of bottomhole assembly (BHA) connections when drilling the 26-in. section through salt. Such overtorque often...

... Abstract As deepwater drilling leapt into the dynamic positioning (DP) era, many drilling contractors and operators lacked an evidence-based approach for identification of potential process safety and well control failure points. Noble Corporation, a global offshore drilling contractor...

...) more than standard SET. The increase provides operators with a critical additional casing string deep in the wellbore. These advances ensure that SET technology will play an increasingly prominent role in HPHT wellbore construction as operators optimize wellbore casing designs and reduce risk...

..., environmental response, etc. The wide range of rules these agencies are responsible for cannot be comprehensively verified with the current infrequency of on-site inspections. Offshore regulation and operational safety could be greatly improved through continuous remote real-time data monitoring. Many...

... Abstract This paper will illustrate the collaborative approach an international oilfield services company and Gulf of Mexico operator used for the planning and successful execution of a 9-7/8-in. x 14-in. Drilling with Liner (DwL) operation to isolate a 6.5 ppg depleted sand interval...

As well as demonstrating compliance, there are other benefits. The solution requires minimal rig time for the landing and spacing out...

... Abstract Maximizing profitability in mature fields is dependent on reducing drilling and operational expenses to maintain optimized hydrocarbon production. As Forties field UK North Sea matures, drilling challenges are becoming increasingly more difficult and complex. Wellbore instability...

... Abstract The Integrated Under-Reamer (IUR) was developed in 2007 in a joint project between an Operator and Service company. The tool was designed to allow for unlimited opening and closing of the tool to provide selective hole opening in unstable formations e.g. unstable shale or swelling salt...

... to the drillstring torquing up and caused frequent rotary stalls. The standard operating surface torque was below 30,000 ft-lbs, but with the excessive stick/slip events, the torque limit of the top drive was reached repeatedly. The drilling dynamics tool in the BHA revealed that in the 12¼-in. x 14-in. hole section...

... Abstract Casing centralization is one of the key elements to ensure the quality of a cementing job by preventing mud channeling and poor zonal isolation. Centralizers can also assist in running of the casing and prevention of differential sticking. The challenge that both operators and service...

A recent application in deepwater Gulf of Mexico (GOM) allowed a major oil and gas company to perform a step change in technology that enabled the operator to perform the function more rapidly and at reduced expense. Swellable packers were used instead of cement, providing a novel...
